Solar Renewable Energy Credits, also known as SRECs, are credits generated by a solar system based on the electricity produced by the system. One SREC is generated for every megawatt hour (MWh), or 1,000 kilowatt hours (kWh), of electricity generated by a solar system. In order to sell your SRECs your solar system must be certified by the Delaware Public Service Commission. For information on the various programs you can sell your SRECs through please visit our SREC page.
